4 Claims.

'fhis invention relates to improvements in tapes orstringers, applied inconjunction with separable slide fastener closures, being specificallydirected to a woven tape, the cord or bead of which is disposedintermediate the edges of the tape or Stringer.

Broadly, it is an object of this invention to provide for a tape -orstringer applied in conjunction with separable slide fasteners, which mtape comprises a lwoven material intermediate the edges of ywhich thereis inserted in the place of certain of the warp threads a cord or' bead,which element is interlocked with the tape or Stringer by' the weftthreads encircling the pela ripheral surfaces of the same.

Specifically, it is an object of this invention to provide a tape orStringer for separable slide' fasteners, wherein there is woven into thetape intermediate its edges, in the place of certain of 20 the warpthreads, 'a cord or bead of dimensions considerably greater than thethickness of the tape, the cord or bead providing a bulge or projectionof equal depth on Opposite sides of the tape or, if desired, of smallbulge on one side and 2g a considerably greater bulge on the other, the

weft being woven so that alternate threads surround the same peripheralsections of the bead or cord and adjacent threads surround oppositeperipheral sections of the bead or cord.

30, Still further, it is an object of this invention to provide for awoven tape for separable slide fasteners, comprising a woven element,into which there is interlocked intermediate of its ends, in lieu ofcertain warp threads, a bead, the

35 bead being adapted to be clamped bythe jaws of a fastener, theportion of the tape on one side of the bead serving to fasten the unitto the de-l vice to which it is applied, and the section of the tape onthe other side of the bead serving o to form a cover for the head of thefastener elements, thereby to provide for the formation of a coveredslide fastener.

These and other advantages, capabilities and features of the inventionwill appear from the subjoined detailed description of one specificembodiment thereof illustrated in the accoinpanyng drawing, in whichFigure 1 is a plan view of the covered separable fastener. j sa Figure 2is a perspective `view of one side 'of the covered separable fastener,showing one of the embodiments of the fastener tape.

Figure v3 is a plan view of the fastener tape. Figure 4 is a frontelevation in section, taken as along lines 4--4 of Figure 3.

Figure 5 is a plan view of a modified form of fastener tape.

Figure 6 is -a front elevation in section, taken along lines 6--6 ofFigure 5. i

Figure 7 is a perspective view of the fastener 5 tape shown in Figures 5and 6 as associated with a fastener element.

Referring to the reference characters in the drawing, numeral I0represents a slide fastener assembly of -the type specified, whereinseries II 10 and I2 of mating fastener elements are disposed inalternation on tapes I3 and I4, slide I5 serving to seal or open theclosure formed by separable fastener elements by reciprocation in amanner well known to the art. l5

Referring specifically to Figures 2, 3 and 4, there is shown a woventape 20, intermediate the ends of which is disposed, in lieu of certainwarp threads, a bead or cord 2l, in this case, of cylindrical formation,said bead being interlocked between parallel series of weft cords 22 and23, the cords 22 being normally adjacent cords 23, the alternate cords22 being parallel and'surrounding the same surface 24 of the bead, whileintervening weft cords 23 surround the 25 same peripheral surface 25` ofthe cord or bead 2|.

In the particular modification shown in Figures 2 to 4, the cord 2| isdisposed so that it projects or bulges substantially away from the lowerface of the tape 2|) in contradistinction to the 30 slight orunappreciable bulge towards the upper face of tape 20. i

As indicated in Figure 2, the cord or bead 2I separates the tapes intotwo parts, the fastening portion 26 and the covering portion 2I. In 35 Vassembly of the fasteners upon the tape, the tape is placed in iiatwisemanner over the top 28 of the fastener element I I, so that the bead orcord portion thereof depends into groove 29 between jaws 30 of thefastener. Upon clamping of the o jaws to position shown in Figure 2, thetape, particularly the bead portion thereof, is enclosed completelywithin the slot 29 and the edges 3l of the jaws 30 press againstsections of the tape adjacent the beadto firmly clamp such 5 portions32, thus locking the fastener to the tape with thefastening attachmentand fastener head cover portions 26 and 2'I of the tape 20 restingflatwise and substantially in one plane on the nat surface 28 of thefastener. 50

so that it bulges equally from both faces of the tape, and the adjacentweft threads 42 and 43 surround opposite semi-circular peripheralsurfaces of the bead or cord and are of substantially the same length,the alternate weft threads being parallel to one another and passing inthe same direction.

As shown in Figure 7, the length of the portions in the fastenerattachment and fastener head cover portions 44 and 45, adjacent the bead4l, which are clamped by the jaws 30 of the fastener II, are muchgreater than that clasped in the other embodiment described, but theclamping action of the jaws and the neck formation produced thereby issimilar in nature, the fastener attachment surface 44 and fastener headcover surface 45 of the tape, after the clamping of the bead 4| by thejaws of the fastener, resting on upper flat surface 28 of the fastener,to produce substantially the same eifect as that shown in the previousembodiment.

It is obvious that various changes and modications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims.

I claim:

1. A scoop-carrying tape for interlocking scoop type slide fasteners,consisting of a series of generally parallel warp threads of relativelys-mall cross-section, a single unbent anchorage warp thread ofrelatively large cross-section adjacent thereto and extending in astraight line, a second series of generally parallel Warp threadsadjacent said anchorage-warp thread, the Warp threads of said secondseries being generally equal in cross-section to the warp threads ofsaid first series and lying on the opposite side of said anchorage warpthread, said second series having relatively fewer warp threads than thefirst series, and a weft thread interlaced generally equally with allthe warp threads to unite them into a unitary fabric structure.

2. A scoop carrying tape for interlocking scoop type fastenersconsisting of an integrally woven structure formed of generally parallelbody warp threads of generally equal cross-section and a single unbentanchorage-warp thread of relatively large cross-section spacedsubstantially nearer to one of the marginal body-Warp threads than tothe other marginal body-warp thread and extending in a straight line,and a weft thread interlaced with all of said body-warp 5 threads andwith said anchorage-warp thread at each traverse thereof to form aunitary structure having the anchorage-warp thread firmly bound in andhaving the selvage edges at said marginal body-warp threads. l

3. A scoop-carrying tape for interlocking scoop type slide fasteners,consisting of a series of generally parallel warp threads of relativelysmall cross-section, a single unbent anchorage warp thread of relativelylarge cross-section adjacent l thereto and extending in a straight line,a second series of generally parallel warp threads adjacent saidanchoragewarp thread, the warp threads of said second series beinggenerally equal in cross-section to the warp threads of said rst seriesand lying on the opposite side of said anchorage warp thread, saidsecond series having relatively fewer warp threads than the firstseries, and a weft thread interlaced generally equally with all the warpthreads to unite them into a unitary'fabric structure, such anchoragethread being positioned in the tape to be disposed at one face andlargely disposed beyond the other face of said tape.
